Automobile shock absorbers are an important part of the automobile suspension system. Their main function is to alleviate and reduce the vibration and impact generated during the driving process of the vehicle, thereby improving driving comfort and safety.
We will look at how to choose automobile shock absorbers from the aspects of common classification, key knowledge, and how to choose shock absorbers suitable for your own car model?
Common classification of shock absorbers
1. According to the structure
● Hydraulic shock absorber
Hydraulic shock absorber refers to a structure that achieves automobile shock absorption through the flow of liquid medium. It is mainly composed of cylinder, piston, piston rod, valve body, spring and other parts. Its working principle is that during driving, the liquid flows through the valve between the cylinder and the piston rod to reduce the vibration of the car when driving.
● Gas shock absorber
Pneumatic shock absorber, also known as air shock absorber, is a structure that uses the compression and expansion of gas to achieve shock absorption. It is mainly composed of compressed gas, piston, piston rod, valve body, spring and other components. Its working principle is that the compression and expansion of gas during the driving process of the car achieves the shock absorption effect on the car.
● Hydraulic-gas hybrid shock absorber
Liquid-gas hybrid shock absorber, as the name implies, is a structure that uses liquid and gas to achieve shock absorption. It is mainly composed of cylinder, piston, piston rod, valve body, spring and other parts. Its working principle is to achieve the effect of automobile shock absorption through the flow of liquid and gas.
2. By type
● Monotube shock absorber
The monotube shock absorber is a type that has only one cylinder to achieve shock absorption. It has a simple structure and low manufacturing cost, but the shock absorption effect is not as good as that of the shock absorber with a complex structure.
● Double-tube shock absorber
The double-tube shock absorber is a type that has two cylinders to achieve shock absorption. It has a complex structure and a good shock absorption effect, but the manufacturing cost is high.
● Multi-tube shock absorber
Multi-tube shock absorbers are a type of shock absorber that has multiple cylinders to achieve shock absorption. Its structure is more complex and the shock absorption effect is better, but the manufacturing cost is higher.
Conclusion
There are different types of shock absorbers. When purchasing shock absorbers, please choose according to the usage environment of your car and the actual roads you drive on.
